Carlsbad Caverns National Park Fun Fact: Carlsbad Caverns National Park hosts a huge bat flight event every summer evening! Around dusk, thousands of Brazilian free-tailed bats swirl out of the caverns in a mesmerizing, tornado-like pattern as they head off into the night to hunt insects. The park even has an amphitheater for visitors to watch this nightly spectacle!
